Intergovernmental Organization Data Set

The purpose of this project is to merge, update, and extend two databases on Intergovernmental Organizations, first developed by the Correlates of War project in 1970 and updated again in 2004 (Michael Wallace and J. David Singer 1970; Jon C. Pevehouse, Timothy Nordstrom, and Kevin Warnke 2004) and formal intergovernmental organizations list developed by Volgy et al. (T. J. Volgy et al. 2008).
